IMPROVEMENT IN AUTOMATIC FAN.

The Schedule referred to in these Letters Patent and making peut of the same To all whom fit may concern:

Be it known that we, CoELLEs'rIN DIERINGER and Monnrs LIN-DAMANN, of- Cincinnati, Ohio, have invented an Improvement in Automatic Fans.

The nature of our invention consists in a machine for putting a current of air in motion, andlthus prevent the troublesomeness and annoyance caused by iiies, mosquitoes, and all those insects that so universally prevail in warm weather.

The follow'ing'is afull description of olu iustmment, reference beinghad to the accompanying drawings, which are made a part of these specifications.

Figure l is a View of the entiremachine, attached to the wall, W, as it appears when ready'for operation,

fastened by screws X.

A, -the frame containing the wheels, U, operated upon by the motive-power or Weight I), which is attached to the arbor or shaft B, by means of a cord, Y.

Attached to the shaft Z is a balance-Wheel, P P, with an adjustable Winch or crank, C, to regulate the distance over which the fan or curtain H shall move, which crank operates upon the hollow-wire fan-frame G, through the connecting-arm V, which is fastened with a pin to the adjustable nut N N, upon the fanfram'e G, which swings upon the rod It, and which rod is secured firmly to the wall NV.

E is a governor or adjustable weight, made hollow, to be filled with bullets or shot if desired, to balance the fanand fan-frame, sliding on the upper part of the hollow fau-frame G, and fastened at any desired point,

-by means of the thumb-screw T.

- F F are movable Weights on the fan-frame G G, to use in regulatingthe velocity ofthe fan.

I I I I I I I are the 'fringe and tassels for softening` the current of air.'

Q, the ratchet to hold the arbor B from unwiuding.

Figure 2. J shows an open section of the motivepower or weight, D, iig. 1,eontaning a quantity of shot, S, that may be increased or diminished through an orifice in the top, at L L. 4

Figure 3. K is the style of the wire rings, Vto which the fan H,vig. 1, is fastened, as shown at x :c :v x, lig. 1.

L is a section of the adjustable weight or governor E, as seen in lig. 1, made hollow, and increased or diminished in Weight by means'of shot S passing through the orifice Y. l

M is an enlarged view of the adjustable weights F F, fig. 1, Wl'lich clasp the hollow fan-frame G, fig. l, and beingin the nature of a spring, are retained at any desired point. A v

N is a section of thel hollow-wire fan-frame G, iig. 1.

O represents the reverse side of the balance-wheel P I), as shown at fig. 1, and the manner in which the adjustable winch or crankv is regulated, by mea-ns of a set-screw on. the back of the balance\vl 1eel, in which there is a groove from near the shaft to the perimeter, as seen at What we claim as our invention, and desire vto selcure by-Letters Patent, is-

-In combination with suitable mechanism for imparting motion to the fan, the balance-Wheel P, adjustable winchor crank O, connectingarm V, with adjust-able nuts N and ian-frame G, having a governor or adjustable Weight, E, and sliding weights F, for regulating the motion of the fan, when all the parts are arranged to operate substantially inthe manner as herein desclibed.
